VENTILATOR FOR HATS AND CAPS.

SPECIFICATION forming part of Letters Patent No. 233,384, dated October19, 1880.

Application tiled February 5, 1880.

To all whom it may concern:

Be it known that I, FRIEDRICH W. WELz, of the city, county, and State ofNew York, have invented certain new and useful Improvements inVentilators for Hats and (laps, of which the following is aspecification.

In the accompanying drawings, Figure 1 represents a side view of a hatwith my improved ventilator. Fig. 2 is a detail vertical transversesection on line a: at, Fig. 3; and Fig. 3, a bottom view of theventilator as detached from the hat.

Similar letters of reference indicate corresponding parts.

This invention relates to an improved ventilating device for hats andcaps; and it consists of a fiat or radially-corrugated cap-plate, whichis supported above a ventilating-aperture in the crown of the hat, thecap-plate being larger than the aperture.

Referring to the drawings, A represents a hat or cap of any suitableconstruction and material, and B a plain or radially-corrugatedcap-plate, which is covered with the same material as that of the hat,and supported by stays a a on an exterior ring-shaped base, I). Thisbase I) is secured tothe edge of a ventilating-aperture in the crown ofthe hat or cap by means of prongs d, which extend to the inside of thehat and are bent over an interior ring-shaped washer, e, of the hat. Inplace of the connecting-ring and washer, any other fastening device maybe used.

The cap-plate B is supported by the stays a a at some distance above theaperture, so as to leave a sufficient space for the escape of the air,which is drawn in through "entilatingholes at the sides of the hat orcap. The capplate B is somewhat larger than the ventilating-aperture, toform a kind of protecting-roof and prevent the entrance of rain.

The ventilator imparts a neat and ornamental appearance to the hat orcap, as it looks like a finishing-button or crown-piece to the body ofthe hat.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a ventilator for hats, the combination, with thehat having a ventilating-aperture in its crown, of a convex cap-platewhich is supported by stays above the aperture and adapted to shed thewater on the crown of the hat outside of the aperture, substantially asdescribed.

2. In a ventilator for hats, the combination, with a hat having aventilating-aperture in its crown, of a convex water-shedding capplatewhich is supported on side stays and attached by an annular ring to thecrown, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 2d day of February, 1880.

FRIEDRICH W. VVELZ.
